Abstract: This paper focuses on the government R&D expenditures and analyses the dynamic reaction patterns of energy R&D in several countries to oil shocks and shows that the oil shocks served as a strong incentive to promote energy R&D. But on the other hand, it suggests the myopic behaviour of government in energy R&D. We further analyse the trends of energy R&D portfolio in both technology dimension and country. The result shows a trend of technological variety, but fewer countries have invested in energy R&D, and those countries tend to invest in their favoured technologies.
Keywords: energy R&D expenditures; portfolios; entropy; diversification; concentration; research and development; government R&D expenditures; national R&D expenditures; oil crisis; energy technology; energy policy.
